Case Studies: ANSI 12.19

Saturn Systems was contracted to develop a C# .NET based driver to communicate with an ANSI 12.19 compliant smart meter over general packet radio service (GPRS). The resulting driver had to be integrated with an existing parser to produce readable data for inclusion in a database. The project required our engineer to quickly understand the depth and complexities of the ANSI 12.19 protocol as well as an undocumented custom parser module. The project resulted in a robust, object-oriented driver framework and common data link layer that supported protocol enhancement and meter specifics. The parser code was also abstracted to support generic 12.19 parsing as well as the easy addition of meter specific data parsing. All code was developed and tested using a custom driver application used to exercise all features and functions supported by the driver.
